GAS-PRODUCER.

SPECIFICATION forming part of Letters Patent No. 635,313, dated October 24, 1899. Application filed November 16, 1898. Serial No. 696,583. (No model.)

To all whom it may concern.-

Be it known that I, WILLIAM GARRETT, of Cleveland, in the county of Ouyahoga and State of Ohio, have invented a new and useful Improvement in Gas-Producers, of which the following is a full clear, and exact de scription, reference being had to the accompanying drawings, forming part of this specification, in which V Figure 1 is an end view, the left-hand half being in vertical section; and Fig. 2 is a longitudinal section on the line II II of Fig. 1.

In Fig. 1 I show my improved gas-producer constructed in conjunction with a heating-furnace and so arranged that the gas as it is produced in the producer will ignite in the upper part thereof and pass in a state of combustion through the furnace.

2 represents the chamber of the producer, into which the coal may be charged through suitable doors 3, located either in the side or front walls or in the top of the combustionchamber.

4 is a grating of inclined and angular form, perforated to admit air from its interior or under side, air and steam being delivered by a supply-pipe 5. This grating is preferably made double, affording a sloping surface on two sides leading down to the base of the combustion chamber into a-water-pan 6, which constitutes a water seal at the base of the chamber.

In the side walls of the combustion-chamber opposite to the sloping surfaces of the grates are wind-boxes 7 7, having perforated gratings 8, adapted to deliver into the combustion-chamber air which is derived from supply-pipes 9.

Within the scope of my broader claims the apparatus may be arranged with but one sloping surface to the grating 4 and with one wind-box 7 5 but the duplicate arrangement which I have illustrated in the drawings is preferable.

The operation is as follows: The fire is first started in the chamber upon a bed of ashes placed therein, and combustion having been well inaugurated coal is fed into the chamber so as to cover the inclined grate-surfaces and air is blown in through the pipes 5 and 9, steam also being preferably blown through pipes in order to force in the air. The steam and air from the pipe 5 enters the bed of fuel through the grating 4t and produces gas,

which by admitting an excess of air through the wind-boxes and gratings 7 is caused to burn. As the coal is consumed, the ashes can be removed from the water-pan 6 at the base and on each side of the sloping grate-surfaces, and as they are removed the fuel will gradually settle down and will be shed by the inclined grate-surfaces into the water-pan at the outer portions of the chamber. The combustion is greatly enhanced by the admission of air from the lateral wind box or boxes 7, which acts to cause the rapid burning of the gases produced by the air at the middle inclined grate-surfaces, and this combustion produces a very efficient result with a minimum waste of fuel. An added supply of air for combustion may be admitted through the firing-doors or otherwise.

I claim 1. A gas-producer having an inclined gratesurface, an air-supply arranged to deliver air through said surface, and an opposite wind-box in the producer arranged to deliver air to the gas formed in the fuel resting on the inclined grate; substantially as described.

2. A gas-prod ucer having an inclined gratesurface and a water seal below the same, an air-supply arranged to deliver air through the grate-surface, and an opposite wind-box in the producer arranged to deliver air to the gas formed from the fuel resting on the grate;

-substantially as described.

3. A gas-producer having inclined gratesurfaces extending across the same and forming an intermediate ridge, an air-supply arranged to deliver air through said surfaces, a Water seal below the inclined surfaces, and wind-boxesin the producer opposite to the inclined surfaces and arranged to deliver air to unite with the gas formed in the fuel resting on said grate-surfaces; substantially as described.

In testimony whereof I have hereunto set my hand.

WILLIAM GA BRETT.
